JPH0716074A - Production of stock enriched with calcium - Google Patents

Abstract

PURPOSE:To produce stock enriched with calcium by adding calcium contained in an eggshell to stock without waste. CONSTITUTION:Eggshell powder is mixed with lactic acid and hot water while stirring or the eggshell powder is mixed with lactic acid and water under stirring while heating to give a solution of calcium. The solution is blended with a stock raw material prepared by powdering dried bonito, dried small sardines, tangle, etc., and stirred. Then the stock raw material is taken out from the solution of calcium and dried.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a calcium fortified broth containing bonito flakes, dried sardines, and kelp as main raw materials.

[0002]

2. Description of the Related Art It has been conventionally recognized that bonito flakes, dried sardines, kelp and the like are used as main raw materials and contain a sufficient amount of calcium.

Actually, it has been confirmed by the test results that the amount of calcium contained in 100 g of dried dairy powder is about 2400 mg.

However, it was found from the test results that, when the soup stock was taken from the dried powder, the soup stock contained only a slight amount of calcium. For example, if 10 g of dried powder and 600 cc of water are heated to obtain soup stock for one standard household (4 people),
Only 4 mg of calcium was dissolved per 100 g of dashi stock.

Therefore, the present inventor considered that it is desirable to add egg shell powder to the above-mentioned powder, since the egg shell contains a large amount of calcium and is inexpensive, so that calcium can be enhanced.

[0006]

However, there is a problem that the egg shell powder is difficult to dissolve in water or hot water, and most of it is deposited on the bottom of the pan even if mixed in the boiling stock.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a method for producing a calcium fortified product using lactic acid which is effective for dissolving egg shell powder. And

[0008]

In order to achieve the above object, a method for producing a calcium fortified product according to the present invention comprises mixing and stirring egg shell powder, lactic acid and hot water, or heating egg shell powder, lactic acid and water. While mixing and stirring to make a calcium solution, dry it in this solution, bonito,
It is characterized in that kelp and the like powdered raw material is mixed and stirred, then the raw material is taken out from the calcium solution and dried.

[0009]

EXAMPLES Examples of the present invention will be described in detail below. First, mix egg shell powder 10g, acidity 90% lactic acid 30g and boiling water 100cc and stir for about 20 to 30 seconds, or
Or 10 g of egg shell powder. Lactic acid with 90% acidity and water 10
Mix 0 cc while heating and stir for about 20 to 30 seconds to prepare a calcium solution. The type of lactic acid may be fermented lactic acid or brewing lactic acid.

In this calcium solution, the mixing ratio of egg shell powder and lactic acid is 1: 3, but 1: 2, that is, lactic acid can be 20 g.

In the former case, even if the calcium solution was allowed to stand for 3 days, the egg shell powder did not precipitate at all. In the latter case,
A small amount of precipitate was observed, but there was almost no problem.

Then, the raw material obtained by pulverizing dried bonito flakes, dried kelp and the like is mixed into the calcium solution and stirred, and then the raw material is taken out from the calcium solution and dried.

For example, when dried sardines are used as the above-mentioned raw material, the dried solids are crushed by a crusher, dried powder is put in a kettle, heat-treated and sterilized, and fragrance is given out. 100 g dried powder dried in this way
The calcium solution is sprayed on the mixture, mixed and stirred with a mixer for about 30 seconds, and then placed in a drier to be completely dried.

Thus, 100 g of dried powder, 10 g of egg shell powder, 20 g of lactic acid for brewing with an acidity of 90% and boiling water 10 were added.
150 ml of soup stock using the stock made at 0cc
Was prepared and the calcium content in the soup stock was measured and found to be 130 mg.

In addition to the dried powder described above, the same calcium fortified powder as above can be prepared by using bonito flakes or kelp as a raw material.

[0016]

EFFECTS OF THE INVENTION Since the present invention is constituted as described above, since egg shell powder having a high calcium content is dissolved by lactic acid, it can be added to the raw materials such as dried bonito, dried sardines and kelp without waste. As a result, it is possible to reliably produce a stock containing much more calcium than the conventional product.
